BACKGROUND Technical Field

The present invention relates to compounds for organic electric element, organic electric element comprising the same, and electronic devices thereof.

Background Art

In general, an organic light emitting phenomenon refers to a phenomenon in which electric energy is converted into light energy of an organic material. An organic electric element utilizing the organic light emitting phenomenon usually has a structure including an anode, a cathode, and an organic material layer interposed therebetween. In many cases, the organic material layer has a multi-layered structure having respectively different materials in order to improve efficiency and stability of an organic electric element, and for example, may comprise a hole injection layer, a hole transport layer, a light emitting layer, an electron transport layer, an electron injection layer, or the like.

Materials used as an organic material layer in an organic electric element may be classified into a light emitting material and a charge transport material, for example, a hole injection material, a hole transport material, an electron transport material, an electron injection material, and the like according to its function. Further, the light emitting material may be divided into a high molecular weight type and a low molecular weight type according to its molecular weight, and may also be divided into a fluorescent material derived from excited singlet states of electron and a phosphorescent material derived from excited triplet states of electron according to its light emitting mechanism. Further, the light emitting material may be divided into blue, green, and red light emitting material and yellow and orange light emitting material required for better natural color reproduction according to its light emitting color.

Meanwhile, when only one material is used as a light emitting material, there occur problems of shift of a maximum luminescence wavelength to a longer wavelength due to intermolecular interactions and lowering of the efficiency of a corresponding element due to deterioration in color purity or a reduction in luminous efficiency. On account of this, a host/dopant system may be used as the light emitting material in order to enhance the color purity and increase the luminous efficiency through energy transfer. This is based on the principle that if a small amount of dopant having a smaller energy band gap than a host forming a light emitting layer is mixed in the light emitting layer, then excitons generated in the light emitting layer are transported to the dopant, thus emitting light with high efficiency. With regard to this, since the wavelength of the host is shifted to the wavelength band of the dopant, light having a desired wavelength can be obtained according the type of the dopant.

Currently, the power consumption is required more than more as size of display becomes larger and larger in the portable display market. Therefore, the power consumption is very important factor in the portable display with a limited power source of the battery, and efficiency and life span issues must also be solved.

Efficiency, life span, driving voltage, and the like are correlated with each other. If efficiency is increased, then driving voltage is relatively lowered, and the crystallization of an organic material due to Joule heating generated during operation is reduced as driving voltage is lowered. As a result, life span tends to increase. However, efficiency cannot be maximized only by simply improving the organic material layer. This is because long life span and high efficiency can be simultaneously achieved when an optimal combination of energy levels and T₁ values, inherent material properties (mobility, interfacial properties, etc.), and the like among the respective layers included in the organic material layer is given.

Therefore, there is a need to develop a light emitting material that has high thermal stability and can efficiently a charge balance in the light-emitting layer. That is, in order to allow an organic electric element to fully exhibit excellent features, it should be prerequisite to support a material constituting an organic material layer in the element, for example, a hole injection material, a hole transport material, a light emitting material, an electron transport material, an electron injection material, or the like, by a stable and efficient material. However, the stable and efficient material of organic material layer for an organic electric element has not been fully developed yet, in particular, it is strongly required to develop host material of the light emitting layer.

The term “spiro-compound” as used herein has a spiro union which means union having one atom as the only common member of two rings. The common atom is designated as ‘spiro atom’. The compounds are defined as ‘monospiro-’, ‘dispiro-’ or ‘trispiro-’ depending on the number of spiro atoms in one compound.

The term “heterocyclic group” used in the specification comprises a non-aromatic ring as well as an aromatic ring like “heteroaryl group” or “heteroarylene group”. Unless otherwise stated, the term “heterocyclic group” means, but not limited to, a ring containing one or more heteroatoms and having 2 to 60 carbon atoms. Unless otherwise stated, the term “heteroatom” as used herein refers to N, O, S, P or Si and heterocyclic group means a monocyclic, ring assemblies, a fused polycyclic system or spiro compound containing a heteroatom.

The term “heterocyclic group” used in the specification may comprise compound comprising a heteroatom group such as SO₂, P═O, etc., as the following compounds, instead of carbon forming a ring.

In contrast, when an element is referred to as being “directly on” another element, there are no intervening elements present.

FIG. 1 illustrates an example of an organic electric element according to an embodiment of the present invention.

Referring to the FIG. 1, an organic electric element 100 according to an embodiment of the present invention includes a first electrode 120 formed on a substrate 110, a second electrode 180, and an organic material layer formed between the first electrode 120 and the second electrode 180 and comprising the compound of the present invention. Here, the first electrode 120 may be an anode (positive electrode), and the second electrode 180 may be a cathode (negative electrode). In the case of an inverted organic electroluminescent element, the first electrode may be a cathode, and the second electrode may be an anode.

The organic material layer may include a hole injection layer 130, a hole transport layer 140, a light emitting layer 150, an electron transport layer 160, and an electron injection layer 170 stacked in sequence on the first electrode 120. Here, at least one layer of the organic material layer may be omitted, or a hole blocking layer, an electron blocking layer, an emission-auxiliary layer 151, an electron transport-auxiliary layer, a buffer layer 141, etc. may be further included in the organic material layer, and the electron transport layer 160 or the like may serve as a hole blocking layer.

In addition, although not shown, the organic electric element according to an embodiment of the present invention may further include a protective layer or a layer for improving luminous efficiency. The layer for improving luminous efficiency may be formed on one side of sides of the first electrode or one side of sides of the second electrode, wherein the one side is not facing the organic material layer.

Preferably, a mixture of compound of Formula 1 of the present invention and compound of Formula 2 of the present invention can be used as host of a light emitting layer. Also, preferably, compound of Formula 2-K of the present invention can be used as host of a light emitting layer.

On the other hand, even if the core is same or similar, the band gap, the electrical characteristics, the interface characteristics and the like may be different depending on which substituent is bonded at which position. Therefore, there is a need to study the selection of the core and the combination of the core and the sub-substituent bonded to the core. In particular, long life span and high efficiency can be simultaneously achieved when the optimal combination of energy levels and T₁ values, inherent material properties (mobility, interfacial properties, etc.) and the like among the respective layers of an organic material layer is achieved.

Therefore, the energy level and T₁ value between the respective layers of the organic material layer, inherent material properties (mobility, interfacial properties, etc.) and the like can be optimized by using a mixture of compound of Formula 1 and compound of Formula 2 or compound of Formula 2-K as host of a light emitting layer in the present invention.

The organic electric element according to an embodiment of the present invention may be manufactured using various deposition methods. The organic electric element according to an embodiment of the present invention may be manufactured using a PVD (physical vapor deposition) method or CVD (chemical vapor deposition) method. For example, the organic electric element may be manufactured by depositing a metal, a conductive metal oxide, or alloy on the substrate to form the anode 120, forming the organic material layer including the hole injection layer 130, the hole transport layer 140, the light emitting layer 150, the electron transport layer 160, and the electron injection layer 170 thereon, and then depositing a material which can be used as the cathode 180, thereon. In addition, an emitting auxiliary layer 151 may be formed between a hole transport layer 140 and a light emitting layer 150, and an electron transport-auxiliary layer may be formed between a light emitting layer 150 and an electron transport layer 160.

In addition, the organic material layer may be manufactured in such a manner that a smaller number of layers are formed using various polymer materials by a soluble process or solvent process, for example, spin coating, nozzle printing, inkjet printing, slot coating, dip coating, roll-to-roll, doctor blading, screen printing, or thermal transfer, instead of deposition. Since the organic material layer according to the present invention may be formed in various ways, the scope of protection of the present invention is not limited by a method of forming the organic material layer.

The organic electric element according to an embodiment of the present invention may be of a top emission type, a bottom emission type, or a dual emission type depending on the material used.

In addition, the organic electric element according to the present invention may be selected from group consisting of an organic electroluminescent element, an organic solar cell, an organic photo conductor, an organic transistor, an element for monochromatic illumination and an element quantum dot display.

Manufacturing and Evaluation of Organic Electric Element

[Example 1] to [Example 15] Red OLED (Phosphorescent Host)

On the ITO layer (anode) formed on the glass substrate, 4,4′,4″-tris[2-naphthyl(phenyl)amino]triphenylamine (hereinafter, abbreviated as “2-TNATA”) was vacuum deposited to a thickness of 60 nm to form a hole injection layer. Then, N,N′-bis(1-naphthalenyl)-N,N′-bis-phenyl-(1,1′-biphenyl)-4,4′-diamine (hereinafter abbreviated as “NPB”) was vacuum deposited to a thickness of 55 nm to form a hole transport layer.

Next, a light emitting layer having a thickness of 30 nm was deposited on the hole transport layer by using compound shown in Table 7 below among the compounds represented by Formula 2-K of the present invention as a host material and bis-(1-phenylisoquinolyl)iridium(III)acetylacetonate (hereinafter, abbreviated as “(piq)₂Ir(acac)”) as a dopant material, wherein the weight ratio of the host and the dopant was 95:5.

Next, (1,1′-bisphenyl-4-olato)bis(2-methyl-8-quinolinolato)aluminum (hereinafter, “BAlq”) was vacuum-deposited to a thickness of 5 nm on the light emitting layer to form a hole blocking layer, and bis(10-hydroxybenzo[h]quinolinato)beryllium (hereinafter, “BeBq₂”) was vacuum-deposited to a thickness of 45 nm on the hole blocking layer to form a an electron transport layer. Thereafter, LiF was deposited to a thickness of 0.2 nm to form an electron injection layer on the electron transport layer, and then Al was deposited to a thickness of 150 nm to form a cathode on the electron injection layer. In this way, OLED was manufactured.

T(95) life time was measured using a life time measuring apparatus manufactured by Mc science Inc. at reference brightness of 2500 cd/in². The measurement results are shown in the table 7 below.

From Table 7 above, it can be seen that the electric element using the compound represented by Formula 2-K of the present invention as phosphorescent host material of the light emitting layer has a lower driving voltage and significantly improved efficiency and lifespan compared to the case where Comparative Compound is used.

Comparative Compounds 1 to 3 and the compounds used in Examples of the present invention are similar in that they have a heterocyclic group as a basic skeleton as an N-substituent of a polycyclic compound. However, in the compound of the present invention, naphtho[2,3-b]benzofuran is bonded to (substituted for) N of the carbazole moiety of the polycyclic core being 5 or more rings via L (single bond or C₁-C₁₂ arylen group), whereas Comparative Compound 1 is different from the present invention in that one of the N-substituents of the N—N 5-ring core is dibenzofuran. Comparative Compound 2 differs from the present invention in that naphtho[2,3-b]benzofuran is bonded to the N-substituent group of the N—S 7-ring core via an anthracene(C₁₄) linkage, and Comparative Compound 3 is different from the present invention in that one of the N-substituents of the N—N 5-ring core is naphtho[1,2-b]benzofuran.

Comparing Comparative Examples 1 and 3, the element characteristics are better when the Comparative Compound 3 comprising 2,3-naphthobenzofuran is used as host than when Comparative Compound 1 in which dibenzofuran is introduced as an N-substituent to the N—N 5-ring core is used.

Comparing Comparative Examples 2 and 3, they are identical in that a naphthobenzofuran is introduced as an N-substituent to the core of the polycyclic ring. However, there is a difference in that Comparative Compound 2 is an N—S 7-membered ring core, and 2,3-naphthobenzofuran as an N-substituent is introduced via anthracene, whereas Comparative compound 3 is an N—N 5-membered ring core and 1,2-naphthobenzofuran is directly bonded to the core. The driving voltage was lowered and the efficiency was significantly improved, but the lifespan was slightly reduced in the case of Comparative Example 3 using Comparative Compound 3, compared to Comparative Example 2.

In the case of Comparative Compound 2, the physical properties of the compound change due to the hetero element characteristics included in the N—S polycyclic compound core, and thus, it seems that the lifespan of the element is slightly improved. However, anthracene being a bulky linking group is introduced between the core and the N-substituent, and thus, it seems that the driving voltage and efficiency of the element are lowered.

On the other hand, in the compound represented by Formula 2-K of the present invention, 2,3-naphthobenzofuran or 2,3-naphthobenzothiophene is introduced as an N-substituent of the polycyclic heterocyclic core, and when a linking group is introduced between the polycyclic heterocyclic core and 2,3-naphthobenzofuran or 2,3-naphthobenzothiophene, the linking group is restricted to a C₆-C₁₂ arylene group (especially, the compound used in Examples is C₆). When the compound represented by Formula 2-K of the present invention was used as host (Examples 1 to 15), the element characteristics were significantly improved compared to Comparative Examples 1 to 3.

Referring to Table 8, this will be explained. It can be seen that Comparative Compound 1 has the highest T1 value, Comparative Compound 2 has the smallest T1 value, and Comparative Compound 3 has a slightly smaller T1 value than Comparative Compound 1, and T1 values of compounds 2-147, 2-152 and 2-158 of the present invention are located in the middle range of these comparative compounds (error range of the median value of the minimum and maximum T1 values of the comparative compounds 1 to 3±0.3).

TABLE 8 Comp. Comp. Comp. compd 1 compd 2 compd 3 2-147 2-152 2-158 T1 2.76 1.76 2.67 2.41 2.38 2.39

The difference in the T1 values in Table 8 suggests that the physical properties of the compound may be remarkably changed depending on the degree of molecular bending and the type of the linking group. It seems that the element characteristics are improved when the compound represented by Formula 2-K of the present invention is used since the compound has an appropriate T1 value for easy red emission compared to the compounds used in Comparative Examples 1 to 3.

The element results of the compound of the present invention and the comparative compounds suggests that the energy level (HOMO, LUMO, T1, etc.) of the compound may vary significantly depending on the type of substituent constituting the compound, the substitution position, and the type of heteroatom and a difference in properties of compound may act as a major factor in improving element performance during the element deposition, resulting in different element results. Furthermore, it can be confirmed that when 2,3-fused DBF/DBT having a linear structure in the direction of condensation of fused DBT/DBF among N-containing polycyclic compounds is introduced as an N-substituent like the compound represented by Formula 2-K of the present invention, this is a structure suitable for improving performance of the element.

[Example 16] Mixed Phosphorescent Host of a Light Emitting Layer

On the ITO layer (anode) formed on the glass substrate, 2-TNATA was vacuum deposited to a thickness of 60 nm to form a hole injection layer. Then, NPB was vacuum deposited to a thickness of 55 nm to form a hole transport layer.

Next, a light emitting layer with a thickness of 30 nm was formed on the hole transport layer, wherein a mixture of a compound 1-61 of the present invention (host 1) and a compound 2-36 of the present invention (host 2) in a weight ratio of 3:7 was used as a host and (piq)₂Ir(acac) was used as a dopant and the host and dopant were used in a weight ratio of 95:5.

Next, a film of a mixture of (8-hydroxyquinoline)aluminum (hereinafter abbreviated as “Alq”) and BeBq₂ in a weight ratio of 1:1 was deposited on the hole blocking layer to form an electron transport layer having a thickness of 45 nm. Next, LiF on the electron transport layer was deposited to a thickness of 0.2 nm and then Al was deposited to a thickness of 150 nm to form a cathode. In this way, the OLED was manufactured.

[Example 17] to [Example 120]

The organic electroluminescent elements were manufactured in the same manner as described in Example 16, except that a mixture of the first host compound (host 1) and the second host compound (host 2) described in the following Table 9 was used as host material of the light emitting layer.

[Comparative Example 4] to [Comparative Example 7]

The OLEDs were manufactured in the same manner as described in Example 16, except that a single compound 1-92, compound 1-160, compound 2-129 or compound 2-143 as listed in the following Table 9 was used as host of the light emitting layer, respectively.

[Comparative Example 8] to [Comparative Example 10]

The OLEDs were manufactured in the same manner as described in Example 16 except that a mixture of Comparative compounds 4 and 6 or a mixture of Comparative compounds 4 and 7 as listed in the following Table 9 was used as host of a light emitting layer, respectively.

Electroluminescence characteristics were measured with a PR-650 (Photo research) by applying a forward bias DC voltage to the OLEDs prepared in Examples 16 to 120 of the present invention and Comparative Examples 4 to 10. T(95) life time was measured using a life time measuring apparatus manufactured by Mc science Inc. at reference brightness of 2500 cd/m². The measurement results are shown in the table 9 below.

From Table 9, it can be seen that the driving voltage, efficiency and lifetime were remarkably improved when the mixture of the compounds for an organic electroluminescent element of the present invention represented by Formula 1 and Formula 2 was used as a phosphorescent host (Examples 16 to 120), compared to element using a single material (Comparative Examples 4 to 7), the mixture of Comparative Compounds 4 to 7 (Comparative Examples 8 to 10).

Comparing Comparative Examples 4 to 10, Comparative Examples 8 to 10, in which two compounds were mixed and used as a host, exhibited improved element characteristics compared to Comparative Examples 4 and 5 using the compound of the present invention represented by Formula 1 as a single host, or compared to Comparative Examples 6 and 7 in which the compound of the present invention represented by Formula 2 was used as a single host.

In addition, the driving voltage of the element is lowered, and the efficiency and lifespan is significantly improved when the mixture of compounds represented by Formula 1 and Formula 2 of the present invention are used (Example 16 to Example 120) than when the mixture of the comparative compounds are used (Comparative Examples 8 to 10).

From these results, the inventors of the present invention believed that a mixture of compounds of Formulas 1 and 2 has novel characteristics other than those of each compound, and thus the PL lifetime for each of these compounds and mixtures were measured. As a result, it was confirmed that a new PL wavelength for the mixture of compounds of Formula 1 and 2 of the present invention was formed unlike a single compound.

It seems that this is because when a mixture of compounds of the present invention is used, electrons and holes move or energy is transferred through a new region (exciplex) having a new energy level formed by mixing as well as the energy level of each substance, as a result, efficiency and lifetime are increased. This is an important example in which the mixed thin film shows exciplex energy transfer and light emission processes when the mixture of the present invention is used.

In addition, when a mixture of a polycyclic compound of Formula 1 which has a high T1 value with high stability to not only electrons but also holes and compound of Formula 2 which has strong hole properties was used, the charge balance of hoe and electron in the light emitting layer increases, and thus light emission occurs well inside the light-emitting layer, not the interface of the hole transport layer. As a result, the deterioration in the interface of a hole transport layer is also reduced, thereby maximizing the driving voltage, efficiency and lifetime of the element. Therefore, it seems that the overall performance of the element was improved due to electrochemical synergy when the mixture of compounds of Formulas 1 and 2 was used.

[Example 121] to [Example 126]

An OLED was manufactured in the same manner as in Example 16, except that the first host and the second host were mixed in a certain ratio as shown in Table 10 below.

Electroluminescence characteristics were measured with a PR-650 (Photo research) by applying a forward bias DC voltage to the OLEDs prepared in Examples 121 to 126 of the present invention. T(95) life time was measured using a life time measuring apparatus manufactured by Mc science Inc. at reference brightness of 2500 cd/m². The measurement results are shown in the table 10 below. Examples 33 and 93 show the results of measuring the elements characteristics when host 1 and host 2 were mixed in a ratio of 3:7 and used as a host as in Table 9.

Referring to Table 10, it can be seen that the driving voltage, efficiency and lifespan are the best when the mixing ratio of the first host and the second host was 3:7, and the element characteristics are deteriorated as the amount of the first host was increased. This is because the charge balance in the light emitting layer is maximized as the amount of the compound represented by Formula 2, which has relatively stronger hole characteristics than that of Formula 1, is increased.
